I have a 4X4 and bigger tires so I don't do as good as some the the guys.
unlloaded - 21-22mpg mixed and driving fast (the 5.9 cummins) loves to go slow 60-65ish
unloaded highway only 60-65 - 25-26mpg
Light trailer -17-18mpg
Heavily loaded (weight and wind drag) -14-15mpg
I have heard that the new 6.7 is not as fuel efficient, but I have no first hand knowledge of that.
for more of a consensus go to one of the many diesel truck forums.
I would avoid powerstrokes that aren't 7.3L
good luck
